And he personally took care of the family too - funeral expenses etc., after King died.

And how did the King children treat him after Coreta Scot King died? They didn't let him give a eulogy and didn't let him sit on the stage. Terrible!
Guess who was invited on stage? Bill Clinton, George Bush etc..
Belafonte had criticize Bush days earlier so the King children disinvited him.
That was typical of Black politics then, as is today. Shameful.
